3. Ray Diagrams
This page is about how we scientists draw diagrams to show how light travels, some bits are straight forward (mirror) but some get very complicated (total internal refraction).
Compulsory Task 4: Refraction Experiment
(value +4 xp)
Refraction can occurs when light moves from one medium to another. If the light waves change speed then they will appear to bend.
This experiment takes, patience, skill and the ability to be accurate.

Task 5: Optical Fibres and Total Internal Reflection
(value +2, +1 xp)
Ask a teacher to show you some optical fibre, the optical fibre demonstration and the endoscope (treat it carefully, it is very expensive!).
1. Research total internal reflection and use this phenomena to explain how optical fibres work.
2. Explain why optical fibres are so much better at carrying information than copper cables.
